Subject: [PATCH 00/12] i3c: Support ACPI and SETAASA device discovery
Date: Wed, 18 Mar 2026 22:57:13 +0530 [thread overview]
Message-ID: <20260318172820.13771-1-akhilrajeev@nvidia.com> (raw)
This patch series adds SETAASA device discovery to the I3C subsystem,
enabling support for SPD5118 temperature sensors found on DDR5 memory
modules. The changes also add ACPI support for all existing DAA
methods like SETDASA, SETNEWDA as well as I2C devices on I3C bus.
SPD5118 and similar devices on DDR5 memory modules differ from typical
I3C devices in their initialization. They use SETAASA broadcast CCC
instead of ENTDAA for address assignment, and per JEDEC specification,
are not required to have a Provisioned ID or implement standard device
information CCC commands (GETPID, GETDCR, GETBCR).
The series enables to describe all I3C and I2C devices on both Device
Tree and the ACPI table, using unified device property APIs throughout
the I3C core and the Synopsys DesignWare I3C master driver.
Please note that the series modifies drivers across multiple subsystems,
like Device Tree bindings, ACPI, I3C and HWMON.
Akhil R (12):
dt-bindings: i3c: Add mipi-i3c-static-method to support SETAASA
ACPICA: Read LVR from the I2C resource descriptor
i3c: master: Use unified device property interface
i3c: master: Support ACPI enumeration
i3c: master: Add support for devices using SETAASA
i3c: master: Add support for devices without PID
i3c: master: match I3C device through DT and ACPI
i3c: dw-i3c-master: Add SETAASA as supported CCC
i3c: dw-i3c-master: Add a quirk to skip clock and reset
i3c: dw-i3c-master: Add ACPI ID for Tegra410
hwmon: spd5118: Add I3C support
arm64: defconfig: Enable I3C and SPD5118 hwmon
